Polarimetry of the superluminous supernova LSQ14mo: no evidence for significant deviations from spherical symmetry

Giorgos Leloudas, Ferdinando Patat, Justyn R. Maund +10

We present the first polarimetric observations of a Type I superluminous supernova (SLSN). LSQ14mo was observed with VLT/FORS2 at five different epochs in the V band, with the obse…

Cross-correlation of gravitational lensing from DES Science Verification data with SPT and Planck lensing

D. Kirk, Y. Omori, A. Benoit-Lévy +89

We measure the cross-correlation between weak lensing of galaxy images and of the cosmic microwave background (CMB). The effects of gravitational lensing on different sources will…

Gamma rays from the quasar PKS 1441+25: story of an escape

A. U. Abeysekara, S. Archambault, A. Archer +103

Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the Universe. The det…

A tidally disrupting dwarf galaxy in the halo of NGC 253

Elisa Toloba, David Sand, Kristine Spekkens +7

We report the discovery of Scl-MM-Dw2, a new dwarf galaxy at a projected separation of 50 kpc from NGC 253, as part of the PISCeS (Panoramic Imaging Survey of Centaurus and S…

Infrared color selection of massive galaxies at z > 3

T. Wang, D. Elbaz, C. Schreiber +29

We introduce a new color-selection technique to identify high-redshift, massive galaxies that are systematically missed by Lyman-break selection. The new selection is based on the…

Exploring X-ray Binary Populations in Compact Group Galaxies with

P. Tzanavaris, A. E. Hornschemeier, S. C. Gallagher +5

We obtain total galaxy X-ray luminosities, , originating from individually detected point sources in a sample of 47 galaxies in 15 compact groups of galaxies (CGs). For the gr…
